Strait of Hormuz

STANDING ASSESSMENT

Strait of Hormuz: Iran announces repeated closures while US and Western navies report traffic continues

The Strait of Hormuz is the maritime passage at the centre of recent confrontations over shipping. Reporting shows Iran and its military bodies, including the Revolutionary Guard and a Central Operations Command, have announced closures and said no vessel may transit without Iranian permission, citing Israeli attacks in Lebanon and alleged US and Israeli violations.

Other sources describe a mixed picture on the water. The US military and Western naval forces have said traffic remains flowing and rejected Iran’s claim to control the strait. Commercial tracking and maritime reports are inconsistent: some data show dozens of transits in a 24 hour window and a handful of detected movements, while other reports say vessels and a US-managed southern transit lane have largely paused or are obeying Iranian orders. The reporting is contradictory on whether the closure has been fully implemented.

KEY POINTS
  • Iran and its military organs have publicly announced closures, linking them to Israeli attacks and US or Israeli violations
  • Iranian authorities say ships need permits or coordination to transit the strait
  • The US military and Western naval forces dispute Iran’s control claim and report traffic is continuing
  • Maritime trackers show mixed activity: 67 ships in 24 hours in one report, Windward recorded 12 transits on 21 June
  • Reports say the southern, US-managed transit lane has largely paused, while some vessels still transit
  • Hezbollah said it would not agree to reopen the strait until Israel declares a comprehensive ceasefire; political threats to impose tolls were also reported
